Polyvinyl chloride reinforcement pipe structure

Abstract

The invention discloses a polyvinyl chloride reinforcement pipe structure which is good in strength and resistance to pressure. The polyvinyl chloride reinforcement pipe structure comprises a film scratching prevention layer, an inner polyvinyl chloride layer arranged outside the film scratching prevention layer, a braided fabric reinforcement layer arranged outside the inner polyvinyl chloride layer and an outer polyvinyl chloride layer arranged outside the braided fabric reinforcement layer. A plurality of annular polyvinyl reinforcing ribs extending in the radial direction and a plurality of transverse polyvinyl reinforcing ribs extending in the axial direction are uniformly arranged on the outer side of the outer polyvinyl chloride layer in a staggered mode. The polyvinyl chloride reinforcement pipe structure has the advantages that scratches on the pipe wall caused by impurities in fluid can be avoided through the film scratching prevention layer, a pipeline is prevented from getting thin continuously, and stability of the interior of a plastic pipe body is reinforced through the braided fabric reinforcement layer; meanwhile, the integrated structure of the pipe body is further reinforced through both the annular polyvinyl reinforcing ribs and the transverse polyvinyl reinforcing ribs which are arranged in the staggered mode, strength and resistance to pressure of the plastic pipe body are greatly improved, plastic pipes can replace metal pipes and are used in more fields, and more value is created for the society.

Description

technical field [0001] The invention relates to a polyvinyl chloride reinforced pipe structure. Background technique [0002] Pipe is a very widely used tool, mainly used for the transmission of various fluids. According to different raw materials, it can be roughly divided into metal pipes and plastic pipes. The metal pipe has higher strength, but higher cost, heavier weight and higher transportation cost. Due to the low cost of plastic pipes and easy processing and connection, various plastic pipes are used more and more in many industries, such as water supply and drainage in the construction industry, petroleum, chemical, steel, mining and many other fields. However, the plastic pipe itself also has great defects, the most important of which is its poor strength and pressure resistance, which is an important factor limiting its application field and scope. Some areas with high pressure cannot replace metal pipes. How to improve the strength and pressure resistance of ...
